Add basic performance tests for git commands that can add data to the object database. We cover: * git add * git stash * git update-index (via git stash) * git unpack-objects * git commit --all We cover all currently available fsync methods as well.

# This test measures the performance of adding new files to the object
|
|
# database. The test was originally added to measure the effect of the
|
|
# core.fsyncMethod=batch mode, which is why we are testing different values of
|
|
# that setting explicitly and creating a lot of unique objects.
